Redox-neutral C?H cyanation of tetrahydroisoquinolines under photoredox catalysis

Redox-neutral cyanation of C?H bond adjacent to a nitrogen atom was achieved by using the combination of a photoredox catalyst and p-toluenesulfonyl cyanide. The reaction of tetrahydroisoquinolines proceeded smoothly, affording the corresponding cyanated products selectively in good to high yield. Although the reaction rate became slower in the case of the substrates having electron-withdrawing groups, high yields were achieved by elongating the reaction time. Although the yields were only moderate, the reaction conditions were also applicable to N,N-dialkylanilines.

Br¡ãnsted Acid Cocatalysis in Copper(I)-Photocatalyzed alpha-Amino C-H Bond Functionalization

We have exploited a bis(1,10-phenanthroline)copper(I) visible light photocatalyst (VLP), [Cu(dap)2]+, to effect the direct alpha-C-H functionalization of amines. To our knowledge, this represents the first example of the oxidation of amines that are ultimately incorporated into synthetic targets by a copper(I) VLP. We have utilized this approach to rapidly prepare unprecedented octahydroisoquinolino[2,1-a]pyrrolo[3,4-c]quinoline frameworks and exploited this process to synthesize a novel aglycone analogue of the natural product incargranine B. Most significantly, our studies suggest that the presence of trifluoroacetic acid (TFA) is crucial in mediating the aerobic oxidative quenching of a putative photoexcited copper(I) species involved in the catalytic cycle.

A Porous and Stable Porphyrin Metal-Organic Framework as an Efficient Catalyst towards Visible-Light-Mediated Aerobic Cross-Dehydrogenative-Coupling Reactions

Porphyrin metal-organic frameworks (PMOFs) are emerging as heterogeneous photocatalysts owing to the well-designed frameworks incorporated with powerful light-harvesting porphyrin chromophores. The porous and stable framework Ir?PCN-224 (which is also denoted as Ir?PMOF-1), which has been prepared by the self-assembly of Ir(TCPP)Cl (TCPP=tetrakis(4-carboxyphenyl)porphyrin) and ZrCl4, is reported herein to be efficient for the aerobic cross-dehydrogenative carbon?phosphorus coupling reaction, giving rise to a high turn-over number (TON) of up to 17200 under visible light irradiation (lambda?420 nm). Electron paramagnetic resonance (EPR) experiments disclose that the active species might be the superoxide radical anion (O2 .?). Additionally, the intermediate imine cation has been detected by high-resolution mass spectrometry (HRMS).

One-pot functionalisation of N-substituted tetrahydroisoquinolines by photooxidation and tunable organometallic trapping of iminium intermediates

Nucleophilic trapping of iminium salts generated via oxidative functionalisation of tertiary amines is well established with stabilised carbon nucleophiles. The few reports of organometallic additions have limited scope of substrate and organometallic nucleophile. We report a novel, one-pot methodology that functionalises N – substituted tetrahydroisoquinolines by visible lightassisted photooxidation, followed by trapping of the resultant iminium ions with organometallic nucleophiles. This affords 1,2-disubstituted tetrahydroisoquinolines in moderate to excellent yields.

Visible light mediated homo- and heterocoupling of benzyl alcohols and benzyl amines on polycrystalline cadmium sulfide

The oxidative coupling of sp3 hybridized carbon atoms by photocatalysis is a valuable synthetic method as stoichiometric oxidation reagents can be avoided and dihydrogen is the only byproduct of the reaction. Cadmium sulfide, a readily available semiconductor, was used as a visible light heterogeneous photocatalyst for the oxidative coupling of benzyl alcohols and benzyl amines by irradiation with blue light. Depending on the structure of the starting material, good to excellent yields of homocoupling products were obtained as mixtures of diastereomers. Cross-coupling between benzyl alcohols and benzyl amines gave product mixtures, but was selective for the coupling of tetrahydroisoquinolines to nitromethane. The results demonstrate that CdS is a suitable visible light photocatalyst for oxidative bond formation under anaerobic conditions.

2D-MoS2 photocatalyzed cross dehydrogenative coupling reaction synchronized with hydrogen evolution reaction

The chemically exfoliated 2D-MoS2 has a mixture of 1T (metallic) and 2H (semiconducting) phases. It has shown a considerably good catalytic activity for hydrogen evolution reaction (HER), proceeding via electrochemical as well as photochemical pathways. Experimentalists have utilized triethanolamine or other sacrificial donors along with Eosin Y as a photosensitizer. But the potential of this reaction has not yet been fully explored as the sacrificial donor is wasted in the oxidation process. The oxidation cycle of this process can be used in many organic transformation(s). Herein, we report the use of the oxidative cycle for efficient cross dehydrogenative coupling (CDC) reaction with tetrahydroisoquinoline and indole substrates as well as their derivatives, parallel to HER. The reaction results in good to excellent yield of the corresponding product under visible light irradiation at room temperature. The mechanistic investigation has also been carried out. This study is a potential example of how to fully harness the oxidation and reduction cycles of many semiconductor based photocatalysts.

Competitive Hydrogen Atom Transfer to Oxyl- and Peroxyl Radicals in the Cu-Catalyzed Oxidative Coupling of N-Aryl Tetrahydroisoquinolines Using tert-Butyl Hydroperoxide

The question of whether hydrogen atom transfer (HAT) or electron transfer (ET) is the key step in the activation of N-aryl tetrahydroisoquinolines in oxidative coupling reactions using CuBr as catalyst and tert-butyl hydroperoxide (tBuOOH) has been investigated. Strong indications for a HAT mechanism were derived by using different para-substituted N-aryl tetrahydroisoquinolines, showing that electronic effects play a minor role in the reaction. Hammett plots of the Cu-catalyzed reaction, a direct time-resolved kinetic study with in situ generated cumyloxyl radicals, as well as density functional calculations gave essentially the same results. We conclude from these results and from kinetic isotope effect experiments that HAT is mostly mediated by tert-butoxyl radicals and only to a lesser extent by tert-butylperoxyl radicals, in contrast to common assumptions. However, reaction conditions affect the competition between these two pathways, which can significantly change the magnitude of kinetic isotope effects.
